Abstract

The invention discloses ecological phosphate fertilizer and a preparation method thereof. Waste phosphorus slag, phosphogypsum, ground phosphate rock and phosphorus vanadium slag of a phosphorus chemical industry can be utilized, so that non-waste discharge, waste into treasures, greenness and environment friendliness of the phosphorus chemical industry are realized. The preparation method disclosed by the invention has the advantages of simplicity, low cost, good market application prospect and capabilities of being produced on a large scale and bringing considerable economic benefits.

Description

technical field [0001] The invention relates to the field of ecological phosphate fertilizer and a preparation method thereof, in particular to a vanadium-containing ecological phosphate fertilizer and a preparation method thereof. Background technique [0002] Along with the rapid development of my country's chemical industry, the phosphorus chemical industry in my country has developed rapidly and achieved encouraging results in the past two decades. There are currently about 300 phosphorus chemical production enterprises in my country, employing more than hundreds of thousands of people, and have formed fixed assets of about 6 billion yuan, accounting for about 20% of the total fixed assets of the national chemical industry. The main products are phosphate rock, sulfuric acid, ordinary calcium superphosphate, calcium magnesium phosphate fertilizer, double superphosphate, yellow phosphorus, red phosphorus, phosphoric acid (including industrial grade and food grade), sodium...
